+### PostgreSQL setup
+
+Install PostgreSQL according to its [documentation](https://www.postgresql.org/download/).
+
+Enter psql, a terminal-based front-end to PostgreSQL:
+
+<div class="termy">
+
+```console
+$ psql -qd postgres
+```
+
+Run the following queries to create the user and database:
+
+```psql
+CREATE USER modmail WITH SUPERUSER PASSWORD 'modmail';
+CREATE DATABASE modmail WITH OWNER modmail;
+```
+
+Finally, enter `/q` to exit psql.
+
+Once the Database is started, you need run migrations to init tables and columns which can be ran through:
+
+<div class="termy">
+
+```console
+$ poetry run alembic upgrade heads
+

+## Applying database migrations
+Migrations are like a version control system for your database. Each migration defines a change to the database
+and how to undo it. By modifying your database through migrations, you create a consistent, testable, and shareable
+way to evolve your databases over time.
+
+You can easily create migrations through aerich's CLI. But before you do that, you need to generate the database
+schemas, this can simply be done by running the bot once (`task start`). Once that's done, you can use the CLI
+to generate the migration raw SQL file:
+
+<div class="termy">
+
+```console
+$ aerich migrate
+
+---> 100%
+
+Success migrate 1_202029051520102929_drop_column.sql
+```
+
+</div>
+
+Now, check your `migrations/models` folder. You should see your brand-new migration! Notice that it also
+contains a timestamp. This allows `aerich` to run your migrations in the correct order. Format of migrate filename
+is `{version_num}_{datetime}_{name|update}.sql`. If you are renaming a column, aerich would ask you for confirmation,
+you can then choose `True` to rename the column without a column drop and `False` to drop the column then create.
+Note that the latter may **lose** data.
+
+
